捕獲交互式Python shell輸出以及輸入

Question

我想捕獲Python shell輸出以及發送給它的輸入。例如，在下面的使用情況下，幫助（）也應存在於capture.log的第4行：

$ echo "help()" | python3 -i > capture.log 2>&1 
$ cat capture.log 
Python 3.4.2 (default, Oct 8 2014, 10:45:20) 
[GCC 4.9.1] on linux 
Type "help", "copyright", "credits" or "license" for more information.

Answer 1

假設類似Unix的環境中，可以捕獲所有tty輸入和輸出與所述script命令：

：

$ script capture.log 
Script started, output file is capture.log 
$ python3 
# python interactive session here 
$ exit 
Script done, output file is capture.log 
$ cat capture.log 
Script started on Thu Aug 18 21:21:55 2016 
$ python3

Type "help", "copyright", "credits" or "license" for more information. 
>>> help()

如果，在這個問題例如，Python是完全由stdin管驅動，目標是獲取管道輸入和Python輸出，您可以通過使用tee命令親近

$ echo "help()" | tee capture.log | python3 -i >> capture.log 2>&1 
$ cat capture.log 
help()

正如您所看到的，輸入和輸出都被捕獲，但它們沒有對齊。
